I use DIY copper coil chiller for wort cooling. It brings down the temp to about 40 C in roughly 10 minutes, but thereafter even if i continue for 15 more minutes, I find it difficult to go below 34 C. I pitch direct at that temp, but thus far no problems. I like your process of sanitized ice for cooling. Can you please let me know how to make sanitized ice. I think this would help me greatly. I use my grandmothers' manual stone grinder to mill malt. It is a laborious process, but I consider it as an exercise routine and do it. It takes about 40 minutes hard work to grind 2.5 kg malt. I would like to post a picture but I do not know how. Can I send it across to you via email, so that you can post it if you find it appropriate.

Boil water and let it cool down. So now your water is sanitized.Use your sanitizer to sanitize an airtight container.Put the boiler and cooled water in the airtight container and freeze it.I always have a container ready in the freezer for an unexpected brewday.A 1.5 to 2L container is great for this.

Thank you very much Sapan. I will try this in my next batch. Your short brew day concept is quite impressive. But since I have all the time in the world to do my homebrew batches, I will go through the usual process through mash tun. Thanks again.
